We purchased a Stearns and Foster mattress set and with in 1 year you could not sleep on the mattress without back pain. I am not satisfied with the store or the manufacturer of the product. I paid top dollar thinking I was buying a top of the line product, only to have it break down in eleven months. I was given a cheap Sealy mattress to use until the issue was resolved and have not heard from the store or manufacture for an additional two months. If I were advertising my product as the best I would certainly take negative comments seriously and do everything to fix tie problem. I can only conclude that the guarantee is not worth the paper it is printed on and the manufactured is only out to make a buck and not service the product they sell. I can not recommend the product or consider buying another Stearns and Foster product.
